As I've mentioned to you, I love this, and would really like to eventually have one. Still thinking of molding a larger version? And yes, I'm putting it out there: any chance of selling it as a complete KIT?

Sure writing is easy: just sit staring at a blank page until the drops of blood start forming on your forehead.

I believe what you are seeing Tim is a fuse used to power the cylinder on and off.But I have been wrong before. If so great idea Rick.Kill two birds with one stone.Add a power switch and fuse at the same time. BD.

Good Day allYes Dave is right it is a fuse holder/ switch, on future slightly larger model ( 20 inch as compared too this 16 inch) I will use one of Kevin McLeod magnetic mission switch so a couple of less end cap penetrations.The pumps I use propel this hull just fine with o head discharge, all the thrust is pretty well straight out the back, I have used these same pumps in 2 different sized flying subs and have great sucess with them.I even hacked off the pump section which left me with a sealed motor which I have used direct drive on my Merriman Skipjack and a couple of my Seaviews.The pumps I purchased from Princess Auto and they run aprox $15.00I have opened up a couple of dead ones and found a motor that is somwhere in the 365-385 rangesame can size but no tell tale markingsOn the Skipjack I ran them on 7.4 lipe with tons of throttel and an apm draw of aprox 1.3a/I steer it differentally but on this model no reverse, on the next one there will be room for reverse thrust with 2 other pumps unless I go with a different propulsion system which I am kicking around in the cranium thinking thing.I hope a package can be put together for this 20 inch wip but first I have too finish the hull then get the cart behind the horse.Rick

Good day all you sub voyeursYes Tim, it is one of the first tests last fall, its a shame I did not have a steady hand filming with the tablet and driving at the same time but a first on both fronts. I am only use too drinking and driving ( my sub in the back yard and not on the road... so you kids pay attention, stay in school and stay of drugs) The cylinder is" 7 1/2 "long and" 2 1/2 o.d , 1/8 wall thickness.Rick
